Question

A five-year-old boy is rushed to the emergency room for a nail that has penetrated his skin. As the PA observes the location of the nail, she makes the comment, "thank goodness you have thick skin there…". Where is thick skin located on the body and how many layers does it consist of?

a. Arm pits and pubic region, 4 layers
b. Elbows and knees, 5 layers
c. Cranium and lumbar region, 6 layers
d. Hands and feet, 5 layers

Answer 1

Thick skin is located on the hands and feet and consists of five layers of the epidermis.

Step-by-step explanation:

Thick skin is located on the hands and feet and consists of five layers of the epidermis. The layers of the epidermis are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. This is in contrast to thin skin, which is found in most parts of the body and consists of only four layers.

Answer 2

Thick skin, which contains five layers of the epidermis including the stratum lucidum, is found only on the palms of the hands and the soles of the feet.

Step-by-step explanation:

The thick skin of the human body is located only on the palms of the hands and the soles of the feet. This skin is referred to as “thick skin” as it consists of an additional fifth layer called the stratum lucidum, which is not found in thin skin covering the rest of the body.

The five layers of the epidermis, from deep to superficial, are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
